The first question is "How can I re-generate the .htaccess file content?" I DON'T WANT TO RE-GENERATE THE .HTACCESS FILE. It is due to this that my website stops working. I need a way to install the script without regenerating my current .htaccess file.

The Inveo team provided the best service and support that we have received from any vendors we have ever used. They did work that was far beyond the scope of the purchase, and for this we are grateful and can certainly highly recommend them to anyone else.
